If you devoted seven and a half hours of your waking life to "Stranger Things 2" last weekend, you're not alone by a long shot. The Nielsen Social Media team also reports that Facebook and Twitter hosted 7.2 million interactions referring to the show within the first three days of its release.

And Stranger Things' season two seems to have carried on where the first series left off after the debut episode was watched by a whopping 15.8 million people according to ratings company Nielsen. I don't have any stats to back that up, but there were way more people talking about the series over the weekend.

Unearthing Netflix's viewership numbers is about as tough as replicating Steve Harrington's hairstyle. Netflix responded to this announcement, saying the company will not take part in Nielsen's service, claiming its data "is not accurate, not even close, and does not reflect the viewership of these shows on Netflix".

Nielsen approached the numbers the same way it tallies its Live+3 ratings for broadcast television. With Netflix last reporting it has more than 52 million members in the U.S., that works out to about 30 percent of its USA subscriber base firing up the sequel. For comparison, The Walking Dead season 8 premiere only managed to reign in 15 million viewers in that three-day period.

The inability of observers to accurately gauge the viewership of Netflix programming has proven frustrating for years. For one, Nielsen's numbers only include people who watch on a TV set.

The controversial scheme-used to measure Stranger Things data-has come under fire from Netflix and its ilk, which have disputed its accuracy. The new season of Stranger Things hit Netflix last week-so how much of Season 2 ended up on the cutting-room floor?
